Advisory Archive
A series of storms since last Friday delivered snowfall throughout the mountains of southwest Montana. Another 4 to 8 inches of snow fell last night, and there is 8 to 12 inches of dense snow on the ground throughout our advisory area. Wind has been out of the west to southwest at 15-25 mph for the past 24 hours, and temperatures this morning are in the mid-20s F. Temperatures will be in the 30s F today and rise to the upper 40s F through the weekend. Wind will remain westerly through the weekend at 10-20 mph with the exception of gusts near 30-40 mph late Thursday to early Friday. Expect showers today to taper off by this evening, and then a few brief showers Thursday and Friday night.
Last night it snowed. Searching online I’m unable to get detailed information as SNOTEL is not reporting and ski areas only have wind data. This morning I wandered out into my yard with a headlamp and measured 6” of snow on my picnic table with obvious wind drifting. I’m guessing that 12+” are in the mountains. Last night upper elevation temperatures dropped into the 20s with westerly winds of 20 mph before they swung east. Today will be cloudy with a few flurries and Wednesday and Thursday look sunny with temperatures rising into the 50s in town.
Over the past 24 hours heavy snow has impacted the mountains. By 2 p.m. on Friday the Bridger Range picked up 18” of new snow while the mountains near Big Sky received over a foot. The mountains near Cooke City and West Yellowstone received 6-8 inches. The northern ranges could see an additional 3-6 inches before the storm is over. The southern mountains could see another 1-3 inches. Winds are 15-25 mph out of the W-NW and temperatures are in the 20s F. Tonight, snow will taper off and temperatures will drop into the mid-teens to low 20s F. Winds will shift to the N-NE. Tomorrow will be dry and temps will warm into the 40s F under partly cloudy skies. Winds will remain light to moderate out of the N-NE.
This morning mountain temperatures are in the 30s F under mostly cloudy skies and winds are blowing 5-20 mph out of the west. Today, a weak cold front pushing down from the north will keep temperatures ten degrees cooler than yesterday. Highs will only reach the low to mid 40s F and winds will continue to blow 5-20 mph out of the west. Skies will remain mostly cloudy through the day, but no rain or snow is expected. A ridge of high pressure builds tomorrow producing a warm and sunny start to the week.
Temperatures reached the low 60s F yesterday and are in the mid-30s to high 40s F this morning. Winds are out of the southwest at 10-20 mph with gusts around 30 mph along ridgelines. Today will be mostly sunny with wind out of the west at 15-25 mph and temperatures in the 50s F. A cold front will bring increased cloud cover this afternoon with cooler temperatures and a chance for showers this evening.
Temperatures reached the mid-50s F yesterday and are in the low to mid-30s F this morning, except in the Bridger Range where temperatures are around 40 F. Winds yesterday afternoon were out of the northwest at 15-20 mph and calmed to 5-15 mph overnight. Today will be sunny with wind at 5-10 mph and temperatures near 60 F this afternoon.
Temperatures warmed to the mid-40s F yesterday and are in the high 20s to low 30s F this morning. Winds yesterday were out of the west-northwest at 30-40 mph with gusts in the 50s. Today will be sunny with wind at 5-15 mph and temperatures near 50 F this afternoon. Tonight and tomorrow will be the warmest part of the week.
Yesterday morning a snow squall dropped 2-4” in the Bridger Range, up Hyalite and at Big Sky. In the mountains, temperatures barely cracked above freezing as west winds blew 20-30 mph with gusts of 45 mph. At 5 a.m. temperatures are in the low 20s under partly cloudy skies. Today will become mostly sunny with mountain temperatures reaching 50F before lightly freezing tonight as ridgetop winds decreasing to 15-25 mph. Today through Friday we are on track to get hit with a massive storm…a solar storm, with temperatures hitting a record breaking 70+F. My pasty white skin doesn’t stand a chance and wearing my favorite tank top is probably a bad idea, and not just because of sunburn.
